COMBINED PIPE AND NUT WRENCH.

Specification of Letters Patent.

Patented May 30, 1916.

Application filed February 26, 1916. Serial No. 80,662.

To all whom it may concern:

Be it known that I, BERT FonBUs, a citizen of the United States of America, residing at Bingham, in the county of Fayette, State of Illinois, have invented new and useful Improvements in Combined Pipe and Nut Wrenches of which the following is a specification.

My present invention relates to an improved combined pipe and nut wrench, which is designed to provide an efficient tool capable of use either as a nut wrench or pipe wrench, and which is simple both in construction and operation. I

My invention consists in certain novel combinations and arrangements of parts as will be hereinafter pointed out and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a side elevation of the wrench of my invention, showing the pipe wrench operative, and the nut wrench inoperative. Fig. 2 is an edge view from the right side of Fig. 1.

In the physical embodiment ofmy invention I utilize a fixed shank 1 formed with the enlarged head 2 which is fashioned with oppositely disposed fixed jaws 3 and 4, the former for nuts and the like and the latter for use on pipes and other cylindrical or round objects. The opposite end of the shank 1 is forked and provided with a pair of perforated ears 5 for the pivot bolt 6 which bolt passes through these ears and also through the toothed end or ratchet head 7 of the handle 8, it being understood that the head is pivoted so that the handle 8 may be swung for the purpose of actuating the tool. In Fig. 1 it will be seen by dotted lines at 9 that the shank 1 is recessed so that the ratchet head may turn freely therein. A pair of perforated guide yokes 10 and 11 are utilized to guide the movement of the movable elements of the wrench.

The rack bar 12 which slides in the yokes 10 and 11 is formed with a jaw 13 which co-acts with and is movable relative to the fixed jaw 3 on the shank 1, and the lower end of this rack bar, at its innerside, is

formed with rack teeth 14, with which the ratchet head 7 meshes. The movable member of the pipe wrench comprises the rack bar 15 formed with the jaw 16 to co-act with the pipe jaw 4 of the shank 1 and head 2. At' itslower end this slide or rack bar 15 is also formed with teeth, as 17 meshing with the ratchet head 7 The slide, or rack, bars are held in place by the utilization of the end bars 19 and of the yokes which confine the rack bars and the yokes are rigidly held to the shank 1 by studs or pigs 20.

The operation of the wrench will be apparent from an inspection of the drawings where the tool is shown in full lines as a pipe wrench and in dotted lines as a nut wrench.- By swinging the handle lever 8 to the right in Fig. 1 it is obvious that the engagement of the ratchet head 7 with the teeth of rack bar 15 will move the bar and bring the movable jaw 16 nearer the fixed jaw 4.- of the pipe wrench, until the proper grasp is had on the pipe between these jaws, the action of the ratchet head at the same time withdraws the movable head 13 from the fixed jaw 3 of the nut wrench. By this means a powerful grip may be secured on the object grasped, and of course the grip will be retained as the wrench is turned in the direction toward which the handle is inclined from alinement with the shank 1. The rack bars are fitted into place within their yokes with their teeth in mesh with the teeth of the ratchet at the proper position, and the end bars of the yokes retain the rack bars against displacement. When gripping an object between either of the pairs of jaws, the power is applied through the handle 8 as usual, and it will be apparent that the article or object is gripped and turned by the same movement of the lever.

What I claim is:

The combination with a shank having a head formed with oppositely extended fixed jaws and retaining yokes spaced below the jaws and fixed to the shank, of a handle having an integral toothed ratchet head pivoted in the end of the shank, there being rack bars with j aws retained in the yokes at the sides of the shank and engaged by said head. 7

In testimony whereof I aflix my signature.
